Folks:
Long story short, I have a unpublished manuscript that a faculty member in my department wrote late 1980's early 2000's. He did the entire thing in troff, eqn, and pic.
The faculty member is still alive. A publisher is interested in the manuscript. I have all of the source files on an old unix machine that still has troff, eqn and pic. It also has groff. This issue is that the pic commands are bracketed by .G1 and .G2 not .PS & .PE. The original machine he would have used would have ran AT&T Sys V on an AT&T 3B20. Below is one of the files. Any thoughts on the .G1 .G2? I can get the files that have only eqn and troff to create postscript, but the .G1/.G2 is not understood by pic. I tried replacing the .G1/.G2 with .PS/PE and it failed. I must be missing another program that uses the .G1/2
Thanks

Btw. The heirloom version of troff is from Solaris SVR4 which should be
quite close the version from the 3B20

As others noted, those are the characteristic preprocessor tokens used
by grap(1).
groff(1) says:
A free implementation of the grap preprocessor, written by Ted
Faber ⟨faber@lunabase.org⟩, can be found at the grap website
⟨http://www.lunabase.org/~faber/Vault/software/grap/⟩. groff
supports only this grap.
Distributors often have a package of Faber's grap. I'm not aware of any
other in circulation. (Happy to be corrected here.)
Please contact the groff list, groff at gnu dot org, if you have any
problems using it to format these documents and/or to note formatting
discrepancies between Unix troff and groff. There will likely be some.
I've noted differences between DWB troff and Heirloom troff, so using
the latter does not guarantee identical rendering, and moreover
DWB/System V troff has some bugs/limitations that Heirloom and/or GNU
troffs have fixed, and some of these can affect formatting.
Here's a list from groff's tbl(1) man page, for example.
GNU tbl enhancements
In addition to extensions noted above, GNU tbl removes constraints
endured by users of AT&T tbl.
• Region options can be specified in any lettercase.
• There is no limit on the number of columns in a table,
regardless of their classification, nor any limit on the number
of text blocks.
• All table rows are considered when deciding column widths, not
just those occurring in the first 200 input lines of a region.
Similarly, table continuation (.T&) tokens are recognized
outside a region’s first 200 input lines.
• Numeric and alphabetic entries may appear in the same column.
• Numeric and alphabetic entries may span horizontally.
One can imagine how a 200+-row table could format differently between
DWB/System V and GNU tbl, without either being "wrong".
Regards,
Branden

This isn’t helpful, but the .G1 .G2 look a lot like Gerber codes used in NC machine tools.

Branden. Thank you. FWIW I have generally found heirloom to be good
enough for rendering most old troff on modern systems such that I can
reasonably read the text. But I suspect your detail is useful to know in
some cases. As they say YMMR. That said I often use the groff tools kits
since it’s what comes with things like brew on my Mac but it burps on
certain macros, particularly when I want to render old man pages or doc
files from old Unix versions with things like .UX macro (which is a PITA).
Thanks again,
Clem

Hi Clem,

I generally get good results with it as well. I frequently compare the
behaviors of DWB 3.3 troff and Heirloom troff with 2-3 versions of GNU
troff (1.22.4 [2018], 1.23.0 [2023], and bleeding-edge development).
Setting aside the issue of extensions (whether to the *roff language, to
preprocessors, or to macro packages), I find that Heirloom fixes many
DWB bugs. I think GNU troff can boast of slightly better terminal
support, although nroff veterans are sometimes scandalized by GNU
troff's terminal output driver (grotty(1)) assuming that it's _not_
talking to a Teletype Model 37, but rather a more-or-less ECMA-48 video
terminal.
To brutally abbreviate the history, for $reasons Unix nroff got frozen
in amber in 1978 with respect to terminal support, and continues to live
in a world where the termcap and terminfo libraries were never written.
Unfortunately, the maintainer of the less(1) pager still presumes
(prefers?) that world.
A previous groff maintainer observed that few of our users operate paper
terminals. (Nevertheless grotty retains support for them with its `-c`
option.)
Anton Shepelev wrote a summary I find admirably concise and blunt:
"`grotty' is not an appendix to a pager, but a program for printing
direct to the terminal. Most terminals support those basic ANSI
control sequences, and many console programs freely use them. If a
pager cannot transparently forward them to the terminal, it is a
problem of the pager, not of `grotty', and having a broken -man
configuration by default to just to appease `less' is stupid."

Yes. Our ms(7) manual ("ms.ms"), originally by Larry Kollar, concedes
its limitations.
--- snip ---
7.1. Unix Version 7 ms macros not implemented by groff ms
Several macros described in the Unix Version 7 ms documentation are
unimplemented by groff ms because they are specific to the requirements
of documents produced internally by Bell Laboratories, some of which
also require a glyph for the Bell System logo that groff does not sup‐
port. These macros implemented several document type formats (EG, IM,
MF, MR, TM, TR), were meaningful only in conjunction with the use of
certain document types (AT, CS, CT, OK, SG), stored the postal addresses
of Bell Labs sites (HO, IH, MH, PY, WH), or lacked a stable definition
over time (UX). To compatibly render historical ms documents using
these macros, we advise your documents to invoke the rm request to re‐
move any such macros it uses and then define replacements with an au‐
thentically typeset original at hand.[10] For informal purposes, a sim‐
ple definition of UX should maintain the readability of the document’s
substance.
┌───────────────┐
│ .rm UX │
│ .ds UX Unix\" │
└───────────────┘
───────────
[10] The removal beforehand is necessary because groff ms aliases
these macros to a diagnostic macro, and you want to redefine the aliased
name, not its target.
--- end snip ---
The point of the `UX` macro was to abstract away the problem of sticking
a footnote at the bottom of the page to acknowledge (or in the Labs'
case, announce) the holder of the Unix trade mark on its first
occurrence.
I suspect the CSRC did not anticipate that the trade mark would ever
change hands, let alone how many times...

* [TUHS] Why groff ms doesn't completely support historical documents

Someone on the TUHS list mailed me privately, prompting me to
write this lengthy apology (in the classical sense) of why groff doesn't
make a certain application easier. I have slightly revised my response.
This message also may serve as a summary of the challenges that need to
be overcome if someone else wants to tackle the job, and potentially
contribute it to groff.
[person creates PDFs of historical Unix documents (many of which are
written using the ms macros) and wishes groff ms made the task easier]
I sympathize. I sometimes render historical documents, so I prescribed
in groff ms's documentation the approach that I take myself. I decided
against trying to support a "-matt" or "-msatt" option in groff because
it's flatly impossible to know which definition of `UX` to use. Even a
date declaration in the document sheds little light, as we then have to
consider the question of whether we want fidelity to the actual state of
the mark at the time of that declared date, or to what would have been
rendered in the author's environment--and they may have been using an ms
that wasn't "up to date" in the same respect. That information, too, is
not recorded in the document.[1]
Providing all the macros _except_ `UX` didn't seem likely to satisfy
users since that's the most important one! It shows up in body text
whereas all the others seldom do--if you can live without the cover page
then, often, you're golden. Except for `UX`.
Finally there is the name collision problem with Berkeley. 4.2BSD and
later ms defined `CT` and `TM` macros (aspects of their "thesis mode")
and once again there's no declarator within the document to tell you
which dialect of ms is in use. This one can be heuristically figured
out with pretty good odds, I suspect, but troff works as a filter--what
was I going to do, write a preprocessor just for this?
(Hmm, maybe grog(1) could do it, and that would be in its wheelhouse.
But there's no point until and unless we reimplement support for
Berkeley thesis mode in the first place [so that grog has an option
argument to report], and that is an undertaking I have demurred.[2])
It seemed like a moderate amount of work for almost zero upside. It's
also hard to validate/verify my work. The only historical troffs to
which I have access are Seventh Edition Unix troff (1979, before
Kernighan) and DWB 3.3 (early 1990s). It's a right pain in the butt to
inspect typesetter output on V7 because I have nothing that emulates a
C/A/T or translates it to device-independent troff output for a
"ditroff"-style device description that Kernighan troff, DWB/Hierloom
Doctools troff, or GNU troff could use.
And even if I had either of those, they'd have to be vetted to a _high_
degree of quality before they'd be fit for purpose; else I wouldn't know
whether I was chasing bugs in the groff ms macros or the C/A/T
emulator/translator.
So, to summarize, I confine my compatibility efforts to _nroff_ output,
and rule the Bell Labs "site" macros out of scope. I feel there is not
much more I can do, and have confidence my results, without resources
that I'm lacking.
I hope this sheds some light on my reasoning.

Branden

Nroff did actually read in the output description from, if I remember
correctly, /usr/lib/termtab/xxx with the argument -Txxx. these where
stripped object files. I have made them for Diable daisy-wheel printers. Some
could create bold characters by overprinting and we once had one with two
print heads, the second head had an italics daisy-wheel mounted.

Yes. When Kernighan refactored V7 troff/nroff for device-independence,
he implemented a similar scheme for each. While for troff, this
resulted in device and font description files, "DESC" and a motley
variety of capitalized one-or-two letter names for fonts, for nroff they
were termed "driving tables", a terminological choice that concealed how
closely they resembled the troff scheme.
Compare, for example:
https://github.com/n-t-roff/DWB3.3/blob/master/postscript/devopost/DESC
https://github.com/n-t-roff/DWB3.3/blob/master/postscript/devopost/R
with:
https://minnie.tuhs.org/cgi-bin/utree.pl?file=V10/cmd/troff/tab.37
https://minnie.tuhs.org/cgi-bin/utree.pl?file=V10/cmd/troff/tab.450
...and the family resemblance seems clear.
> these where stripped object files.
I have heard tell of a "binary format" for Kernighan troff device and
font descriptions but never encountered it. groff never attempted to
replicate it and I gather that Plan 9 troff also discarded it.

Right. The Diablo features heavily in early '80s Unix documentation.
However none of this has much to do, in my opinion, with the _terminal
capability databases_ offered by termcap and (later) terminfo. The
whole point of these is to _query_ the user's terminal type, not have to
be told it with some `-T` option.
To my knowledge, no nroff has ever simply looked at "$TERM" and then
decided how to format output. Approximately all other Unix software
that writes to a terminal behaves that way. nroff didn't, and by God
some Unix grognards would have it stay that way.[1][2] Mark Nudelman's
less(1) is probably the foremost contributor of inertia here, since
man(1) is far and away the leading application of nroff(1), and less(1)
the victorious pager program after a long and bloody campaign of
attrition. (This isn't a complaint; we could have done worse. most(1)
could have won instead.[3])
Lennart Jablonka has contributed a patch to groff to resolve this
longevous discrepancy. (It ended up on my slow path for integration
because I decided I needed to understand terminfo much better, and that
in turn led me to contribute a large volume of man page revisions to
ncurses, many of which can be enjoyed(?) in its 6.5 release.[4])

Despite his grognard standpoint with respect to grotty(1)'s default
use of SGR escape sequences in output, I would emphasize that Thomas
Dickey has been a pleasure to work with. It's difficult to imagine
the same being true of Alan Curry.

For years JHU had a KSR37 with a Greek box and nroff drove it direcly
sending all those ESC-8 and ESC-9 things. There were some output
filters that converted this to things like the Diablo daisy wheels and
even the rather crude dot matrix lineprinter we had.
Eventually, George Toth, one of our programmers came up with the idea of
building a C/A/T simulator. He went to the Naval Research Lab and
printed out a full typeface on film from their CAT. He then cut them
out and glued them to the front of an oscilliscope, one letter at a
time.
There was a PDP-11/20 that ran a Scanning Transmission Electron
Microscope (at the time one of the few in captivity). He would take
the scanning driver cables from the microscope and put them on the X/Y
of the oscilliscope and then took the sense wire and put it on a
photomultiplier tube that was mounted in a scope camera. He then fired
up the (DOS/BATCH) microscope software to tell it to do a scan. He’d
then swap the RK05 packs and bring up Minunix and read his scanned
character out of the frame buffer.
One character at a time he accumulated an entire Roman, Bold, Italic,
and Symbol set. He wrote the emulator and we could TROFF through his
software to the Versatec lineprinter we had. The chemicals from those
printers makes my skin break out just thinking about it. It was the
only printer we had at BRL for political reasons for quite a while. It
also would eat the ink of the government issued (made oddly by a
workshop for the blind) pens.

I don't see the problem, less supports -R for the last 25 years...

Yeah. People's ire seems to rise from the fact that grotty's default is
to assume SGR support and less's default is to not interpret SGR.
I would prefer that `-R` were less's default; that would better serve
the larger proportion of ECMA-48 video terminals using the pager versus
those using it with (an emulator of) hardcopy terminals.
Whatever transition process needs to commence for that to happen, I
think it should.
But in the meantime it's no great effort for me (nor for most people) to
alias 'less' to 'less -R', write a shell function to do similarly, or
just type three more characters.
(For those requiring accessibility assistance, shell aliases and
functions, programmable key bindings, and similar should serve as they
do the merely impatient.)

Hello group:
BTW:, I love all the comments and discussions this started.
Using Groff (eqn+pic) + grap I was able to create a PDF of the book. It took about 8 hours part of which was figuring out the syntax differences. He had divided the book up into a file for each page or two, so 100+ files. I think he did that, so he did not waste paper since he had to print out the pages to see if they looked right, no display to view them. It was not perfect but is good enough for the publisher to review. The book is on filters (EE book) and is full of graphs, circuits, and equations. He used pic to draw the circuits, which was amazing. This was fun to take a forgotten manuscript written by a colleague and with luck maybe getting it published while he is still alive. If the publisher wants to publish it, I'm not sure how they will handle troff files :)

Oh, wall clock time including human engagement. That sounds really
reasonable! I'm not sure I want to estimate how many hours I've put
into revising groff's own documentation. Or ncurses's.
Eight hours processing time on a modern machine (without inflooping)
would be shocking to me.

No PostScript or PDF preview program? I can think of a few: mupdf,
evince, okular. Deri James (groff developer) can probably name a dozen.

If you'd care to share it with me in my capacity as groff maintainer,
I'd be interested to use it for unofficial regression testing.
Alternatively, if you can't find an interested publisher, please
consider asking the author (I assume he's also the copyright holder) to
release it under a Creative Commons license so the whole world can
enjoy. Also, so I can selfishly enjoy the pleasure of pointing to a
sophisticated typeset work and saying, "look what groff can do!" ;-)

8 hours of my time, not computer time.
The faculty member started this in 1988, and we (the department) did not have access to much in the way of visual previewing. He was an EE by training, and really latched onto Unix, vi, troff, etc. At the time we were running a series of AT&T 3B2/5, and a 3B20. My wife was sysadmin and I was on the faculty. We had a large number of faculty and staff using troff for editing and publishing. I remember my wife teaching Unix and Troff to faculty. We did have a few of the AT&T graphics terminal (I cannot remember the model number) Another fun thing, I used troff and vi (on a different) system to write my Ph.D. in 1985.
I will reach out to you about the files etc. He is the copyright holder. His health is not good, and his family with the help of a former student is the one hoping to get it published.

I got a chuckle because apparently an old quote of mine is enshrined in
the GROFF documentation (under the debugging section):
Standard troff voodoo, just put a power of two backslashes in front of
it until it works and if you still have problems add a \c. — Ron Natalie
Thanks, G. Branden Robinson, for calling it to my attention.
More nroff fun and games: My first job out of college was working on a
restricted government project on RSX-11/M. I’d been doing various
UNIX and n/troff stuff for years at JHU.
The QA people decided to go all PWB on this project using SCCS etc…
I knew that Denis Mumaugh at the NSA had written nroff macros to do
classification markings automatically.
I asked for a copy, but he couldn’t figure out how to get a tape to me.
I reimplemented it myself. Originally, I had the idea of processing
each marked paragraph into a diversion but
that was problematic. I then just output the footer and then “reverse
fed” the paper back to the top to add the top classification. Of
course, you had to run your nroff via col to
get it to print right.
I also fixed the line printer spooler to catch classification markings
and mark them pages appropriately as well. All this I did while
waiting the 11 months for my ‘beyond TS’ clearance to arrive.
Seems like everybody on the project failed their polygraph the first
time. Examiner must have had a hard seat on the bus from the east
coast.
This was also the project where I had this exchange:
Bernie: What’s all this Bell System crud in the editor?
Me: It’s UNIX. It’s all Bell System crud.
I walk around to his terminal and see this:
$ 1
One Bell System. It works.
$ 1
One Bell System. It works.
Me: You’re not in the editor, Bernie.
After that the /usr/bin/1 command was changed to
echo “You’re not in the editor, Bernie.”

*roff has so spectacular a backwards compatibiliy that its mod-
ern implementaions will not only accept a source from the 1970s
but actually produce a historically accurate rendition of it.
Unlike MS Word, *roff the kind of software that you need not
bother to keep an old version to open your old files.
I therefore suggest that you install a modern *roff and seek as-
sistance with your task in its community. GNU Troff is the only
one I know and use (even for this e-mail), can recommend it for
both hard (the program itself) and soft (the friendly community
and great maintaner) qualities. They are also interested and
successful in recreating historial documents, so feel free to
ask in their mailing list.
